Please explain the following question and answer all
29) cDNA to build libraries that contained DNA copies of mRNA from cells and tissues.
ANSWER IS D
30) Answer is C
Mutations in the HEXA gene cause Tay-Sachs disease. The HEXA gene provides instructions for making part of an enzyme called beta-hexosaminidase A, it plays a critical role in the brain and spinal cord.development
Beta-hexosaminidase A helps break down a fatty substance called GM2 ganglioside.

cDNA libraries are constructed by using reverse transcriptase to synthesize DNA from mRNA that has been isolated from a cell. Since cDNA libraries represent mRNA sequences found within a cell, which of the following would be missing from a gene's sequence in a eukaryotic cDNA library? A) a start codon B) exons C) a signal sequence for polyadenylation D) introns E) a stop codon The following results were achieved after performing an Ames test by exposing his- bacteria to four...
What is the Central Dogma of genetics? -- EXPLAIN Corynebacterium diptheriae, the causative agent of diptheria, secretes a toxin that enzymatically inactivates all molecules of elongation factor in a eukaryotic cell. What immediate and long-term effects does this have on the cellular metabolism of an infected person? -- EXPLAIN What is the difference between horizontal gene transfer and vertical gene transfer? -- EXPLAIN After running gel electrophoresis, what do the black bands represent? What can those bands tell us, and...
